Description

(54) DEVICE FOR SPIRAL GUIDELINES

one

The invention relates to the field of processing materials by pressure, in particular, to equipment for the manufacture of coils with a small internal diameter, which can be applied in the manufacture of 5 bodies of heat of electric lamps.

It is known a device for winding spiral I containing a spindle winding unit mounted along the process, a wire spool mounted on the winding unit.

However, the known device does not provide winding of the wire to the core.

A device for winding a helix 2 is known, comprising a spindle winding unit mounted along the 15-way process, a wire spool and a tensioner.

A disadvantage of the known device is its low reliability.

The closest in technical essence is a device for winding a helix 3 containing a spindle mount and core mounted on a bed in the course of the technological process, a coil 25 with a thread stitched on a core, and a mechanism of translational movement of a core with a helix.

A disadvantage of the known device in its low reliability.

The aim of the invention is to increase reliability by maintaining a constant tension of the winding thread.

The goal is achieved by the fact that in a known device for winding a helix containing a spindle core winding unit mounted on the bed during the technological process, a coil with a thread wound onto the core, a translational movement mechanism of the core with a helix, a translational movement mechanism of the core with a helix is implemented in a factory mounted concentrically on the frame and having different rotational speeds of the carrying and guiding spindles, the latter of which has deflecting rollers, and the carrying spindle has a winding mechanism and tension of a core with a helix consisting of a pulling disk and a retarded core coil coaxially mounted along the spindle, one tilted one; the other roller is placed along the core axis and the other two are located above the pulling disc and braked coil .

FIG. 1 shows a coiling device for a helix; in fig. 2-spindle core coiling unit; in fig. 3 - the mechanism of the forward movement of the core; in fig. 4 - knot of winding thread.

The spiral winding device contains a core core reeling unit 1, a kerium with helix translational mechanism 2, core 3, (coiled thread reeling unit 4, a winding thread 5, an electric motor 6 and a transfer mechanism 7 from the electric motor to the mechanism 2.

The spindle mechanism 1 consists of an electric motor 8, mounted on a shaft of a mandrel fixedly on its shaft 9, on which a coil 10 is mounted, elastically braking elements 11, a nut 12, guiding parts 13.

The mechanism 2 consists of a guide spindle 14 with deflecting rollers 15, (by a tongue) driven rotation transmitting element 16, sub-carriers 17 placed in the housing 18. The guide spindle 14 has a support 19 with a supporting spindle 20, which is fixed on it with a nut 21 t night drive 22.

On the bearing spindle 20 is also installed the coil 23 winding spts-and, wound on the core, the braking elements 24 and the driven element 25 of the transfer.

The coiled yarn winding unit 4 has a fixed 1Crontier shteyn 26, on which the axle 27, the cleaning and brake clamps 28, the details of the force measuring and the direction of the thread being threaded, and the threaded yarn 30.

Device for winding a spiral works as follows.

The electric motors 6 "8 operate simultaneously with the same rotational speed. The electric motor 6 by means of the transmission mechanism 7 transmits rotation on the guide clamp 14 with one gear ratio and on the bearing splitter 20 with another gear ratio, which is selected depending on the required spiral stitch 3 on the continuous core 3. The transmission gear 7 can be made in the form of two parallel belt transmissions, in connection with which the driven elements of the transmission (16 and 25) are depicted as shchivs. The spiral wound core 3 passes along the guides of parts, bends around the pulling disk 22, then winds onto the winding coil 23, which has the ability to rotate on the bearing spindle 20 with braking of the brake elastic members 24. Due to the difference in the speeds of rotation of the spindle 14 and the supporting rod The core 20 is wound onto a pull disk 22, which pulls it progressively in the direction indicated by the arrows (see Figures 1, 2 and 3). In this case, the core 3 is unwound from the reel 10, which has the ability to rotate on the mandrel 9, brake using elastic brake elements 1.1. At the same time, the linear core section

between the spindle assembly 1 of core winding 3 and the spiral winding mechanism 2 wound on core 3, it participates in rotation around its axis under the action of deflecting rollers 15 and parts 13, which rotate at the same speed. At the same time, the thread 5 is wound on the core 3, which is unwound from the freely turning roller 30, is braked by the cleaning-brake clamp 28 and goes through parts 29 of the force measurement and the direction of the thread.

Due to the fact that the rollers 30 with the winding thread 5 does not participate in the rotational movement of the winding of the thread 5 onto the core 3, being placed on the fixed bracket, improved conditions are created to maintain the constant value of the longitudinal tension force of the winding thread and thereby reduce its breakage in the process of spiraling. Therefore, this coiling device on a continuous core can be used in a tungsten wire tester for spiralization, as well as a mechanism for spiraling tungsten filaments, especially thin ones, which are prone to increased breakage.

Such a design of the device for the navigation of the helix significantly increases its reliability of maintaining a constant tension of the winding thread on the continuously moving core.
